1) In the class ImageCRUD.java I have the following code:
_____________________________________________________________________
| public ResultSet listImage(){
| ...
| ps = conn.prepareStatement("select idImage, Name from images");
| return ps.executeQuery();
| ...
|_}___________________________________________________________________
2) In the Servlet ImageServlet.java I have the following code:
_____________________________________________________________________
| ResultSet rs = ic.listImage(); // ic = new ImageCRUD Object
| ...
| request.setAttribute("rs", rs);
|_____________________________________________________________________
3) In the JSP ShowImage.jsp I have the following code.
______________________________________________________________________
| <%
| rs = request.getAttribute("rs");
| while(rs.next()){
| int numColumn = rs.getMetaData().getColumnCount();
| for(int i=1; i <= numColumn; i++){
| out.println(rs.getObject(i));
| }
|}%>
|______________________________________________________________________
I think that rs is null and also I see a blank page.
Where mistake?
Thanks in advance.
